Great Woodswallow

The great woodswallow, also known as the greater woodswallow, giant woodswallow or New Guinea woodswallow, is a species of bird in the family Artamidae. As its name implies, it is the largest member of the genus Artamus, averaging 20 centimetres (7.87 in) in length and 61 grams (2.2 oz) in mass. The great woodswallow is very similar in appearance to the more widespread white-breasted woodswallow, but it can be distinguished by its darker black upper side plumage and by the presence of a semi-oval black patch below the throat.
